The GPS tracker is a terminal with a built-in GPS module and a mobile communication module. The GPS tracker is used to transmit positioning data obtained by the GPS module to a server on the Internet through a mobile communication module (gsm/gprs network) so as to be implemented on a computer or a computer. Query the terminal location on the phone.

GPS Tracker Definition

A GPS tracker essentially contains GPS module to receive the GPS signal and calculate the coordinates. For data loggers it contains large memory to store the coordinates, data pushers additionally contains the GSM/GPRS modem to transmit this information to a central computer either via SMS or via GPRS in form of IP packets. The diagram depicts hardware architecture of an advanced GPS tracker.

Usually, a GPS tracker will fall into one of these three categories, though most smartphones, being GPS Phones, can work in all these modes, depending on which mobile applications are installed: Data loggers, Data pushers, GPS Personal tracking, Asset tracking and so on.

Usage of GPS Tracker

GPS trackers are used to control the whereabouts of children and the elderly, highway patrol, precious cargo tracking, Tracking and Dispatch, private detective tools, personal belongings tracking, pet tracking, wildlife tracking, freight industry, car alarm, bicycle theft, electric vehicle anti-theft, anti-theft motorcycle gps tracker, bank armored cars, police exercise control, prosecutors tracking, official vehicle management

GPS consists of three separate parts:

● Space section: 21 working satellites and 3 spare satellites.

● Ground support system: 1 main control station, 3 injection stations, 5 monitoring stations.

● User equipment section: Receive GPS satellite transmission signals to obtain necessary navigation and positioning information. After data processing, complete navigation and positioning work.

GPS receiver hardware generally consists of a host, an antenna, and a power supply.
